Context
The Institut Laue-Langevin (ILL), situated in Grenoble, France, is Europe's leading research facility for fundamental research using neutrons. The ILL operates the brightest neutron source in the world and hosts over 2000 visits by scientists per year, who come to carry out world-class research. We are looking a Physicist Engineer to design and implement hydrogen test benches for prototype fuel cells and H2 electrolysers at major Research Infrastructures (RIs).
This role supports the EU-funded ACTNXT project, aimed at accelerating the green transition via Power-to-X (PtX) technologies. The PtX community highlights the need for multi-modal characterisation (neutrons, X-rays) and robust hydrogen test benches to enable advanced operando studies at RIs.

Your tasks
You will interact with the groups within the ILL responsible for scientific instruments, industry partnerships, sample environment and European projects, and will be responsible for the following tasks:
. Work closely with the ACTNXT consortium to help ensure the progress of the project, including ILL's specific contribution.
. Establish design criteria for hydrogen fuel cell and electrolyser test benches that meet users' scientific needs, both current and envisaged, for operando, high-throughput and accelerated ageing studies.
. Lead the design, build and commissioning of safe, robust, portable, and easily operable test benches for RIs and users.
. Draft related documentation: functional design specifications, operational and maintenance guides.

Your profile
. Physicist Engineer with a Level 7 qualification (Master's degree)
. You have a comprehensive knowledge of hydrogen test bench technologies and preferably a working acquaintance with neutron and synchrotron X-ray techniques.
. You must be at ease working in a large, international community of users and experts, and have a high degree of autonomy.
